It is designe for production in bad environment and serious interference, with the feature of magnetic interference resistance, shake resistance, electromagnetic radiation resistance, ranning stably, and easy maintenance.

1. With microcomputer processing system and symmetry detection probe in the channel, the signal is even and precision, can effectively distinguish between the interference signal and the detection signal, to improve detection efficiency;

2. The amount of qualified products, unqualified products and the total amount of products can be calculated;

3. Automatically adjust the belt deviation, the belt will not be wandering;

4. Has the alarm system when the belt leaves the normal track, to ensure the life length of the belt as long as it can be;
